Disappointing service at MTN Alberton banch

Very disappointing service at your Alberton branch. I went there after receiving advise from one of the consultant's at the MTN The Glen branch regarding my issue with my pocket router. I was guaranteed that, the branch were I purchased my router will be able to assist me. I got to the Alberton branch that has more than 10 staff members on the floor, others are busy chatting to their friends, while others are on their phones. They all have no concern about their service time. I waited close to 30mins in 2 intervals. The first encounter I was told that it's better I buy a new router because unfortunately the warranty doesn't cover over charged battery faults l, of which I understood. The lady advised that I purchase a pocket router for R249 and failed to tell me that it was out of stock. I told her I will be returning in a Short while to fetch cash from my car. I came back the second time waited another +-30mins to be assisted, just to be told the router I was advised on was no longer in sale and now the router will cost me R449. A 10mins walk out of the store the price has changed. On top of that I'm told to take a drive to another store to check if they can help wow. Can someone please contact me I want to cancel my contract. One thing MTN and their staff seem to forget, there are many companies out there looking for clientele. If you can't offer the service needed another will. I'm done thank you. Please call me with an invoice to cancel. I will just pay someone else who needs me as their client, who will offer valid advise with consistent prices.
